Protective housings for a system

Abstract

An apparatus for filtering and / or purifying and / or conditioning a fluid comprises a pressure vessel having an inlet for introducing fluid into the pressure vessel and an outlet for removing fluid from the pressure vessel, filtering medium positioned inside the pressure vessel for filtering and / or purifying and / or conditioning fluid, and a shell surrounding the pressure vessel, the shell having sufficient anti-flammability properties to be resistant against fire to protect the pressure vessel from fire.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to housings for systems, and more particularly is concerned with protective housings for a system that protect the system from its environment and that protect the environment from the system, wherein the protective housings include a first or inner housing for holding the system and a second or outer housing surrounding the first or inner housing and the system held therein, and wherein the first or inner housing is compatible with the needs of the system and the second or outer housing has sufficient properties to provide protection against damage caused by outside agencies found in the environment of use of the system.[0003]2. Description of the Prior Art[0004]Generally, a housing around a system protects the system from its environment. For example, a housing may provide protection of a system contained or held in the housing by blocking one or more outside agencies, such as objects, sunlight,...

AI Technical Summary

Benefits of technology

The invention is an apparatus that protects a system from damage caused by outside agencies. The apparatus has two housings: one for holding the system and another for protecting it from external damage. The apparatus also includes a pressure vessel for filtering and conditioning fluids, with a flammable shell to resist fire. The technical effect of this invention is to provide a safe and reliable system for protecting and filtering fluids in various environments.

Problems solved by technology

However, there are other instances where the housing meets the needs of the system, such as the structure and support requirements of the system, but does not meet the protection requirements demanded by the environment in which the system is used.

While the polypropylene pressure vessel has sufficient strength to handle the pressure created within the pressure vessel and polypropylene is compatible with the production of potable water, polypropylene is flammable.

Accordingly, while the housing, that is, the polypropylene pressure vessel, meets the needs of the water filtering / purifying / conditioning system to enable the production of potable water, the polypropylene pressure vessel does not protect the water filtering / purifying / conditioning system against catching on fire if a fire broke out in the galley.

For example, polymers that meet the anti-flammability requirements desired for a water filtering / purifying / conditioning pressure vessel used in the galley of an airplane are not strong enough to handle the pressure created within the pressure vessel and / or are not compatible with producing potable drinking water or may be excessively expensive, heavy or sub-optimal in other attributes.

Therefore, a problem exists where a housing meets the needs of a system, but does not meet the protection requirements demanded by the environment in which the system is used.
